Help with internet?

I have been trying for 8 months to get internet from at&t were told initially we could not get homephone or internet after 6 months we finally recieved home phone they simply said it would work within five minutes and nobody even came out. We are unable to get internet through them which is odd since our neighbor gets internet through att and there was a box in front of our house they originally got internet from however it was ripped out of the ground and two houses down in eye view is an att underground cable box, and three houses down there is fiber optic internet buried however according to att we cannot even recieve dsl.

I've been fight for months to get internet should i go above the service representitives and go contact corperate? How do you do that? Have any other had this issue? If so how was it resolved?

It is frustrating being surrounded by internet and being told we cannot get internet service.
